我想使用简单的 Java 获取两个日期之间的日期名称，而不使用任何第三方库。
我想要获取两天之间的名称，例如星期六、星期日、星期一(包括这两天)。
最佳答案
/**
*
* @param startDate
* @param endDate
* @return Start Date and End Date are <b>Inclusive</b>, days returned between these two dates
*/
protected List<String> getWeekDayNames(Date startDate, Date endDate) {
List<String> days = new ArrayList<String>();
Calendar startCal = Calendar.getInstance();
startCal.setTime(startDate);
Calendar endCal = Calendar.getInstance();
endCal.setTime(endDate);
if (startCal.getTimeInMillis() == endCal.getTimeInMillis()) {
days.add(this.formatDayOfWeek(startCal.getTime()));
return Collections.unmodifiableList(days);
}
// swap values
if (startCal.getTimeInMillis() > endCal.getTimeInMillis()) {
startCal.setTime(endDate);
endCal.setTime(startDate);
}
do {
days.add(this.formatDayOfWeek(startCal.getTime()));
startCal.add(Calendar.DAY_OF_MONTH, 1);
} while (startCal.getTimeInMillis() <= endCal.getTimeInMillis());
return Collections.unmodifiableList(days);
}
用法:
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DAY_OF_MONTH, 15);
List<String> list = new Test().getWeekDayNames(new Date(), cal.getTime());
System.out.println(list);
输出:
[SATURDAY, SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY]
